Abstract

This paper proposes an improved incremental conductance (INC) method to address the variability of solar irradiance in maximum power point tracking （MPPT）. Based on the MPPT algorithm, the photovoltaic power generation model is established in Matlab/Simulink, and its feasibility is verified. The six photovoltaic modules with the same temperature conditions are used to verify the performance of the algorithm. Simulation results in Matlab/Simulink show that the improved increment conductance method has better maximum power tracking performance than the traditional increment conductance method. Experimental results show that the improved increment conductance method achieves approximately 4.33% higher maximum power tracking efficiency than the traditional increment conductance method.
